Just looking to get an overview of what the new items do, as I’m not sure I completely understand what they do. Here are the ones that I’m aware of:
Infection Cleaner - I think that’s the name. It’s the SMG. Seems like it’s just a reskinned Avenger locked to a Fire element.
Toothpick - Wierd fire pattern. May be a reskin of one of the Assault Rifle Pearls, but I’m not sure.
Mouthwash - Increased damage for the Toothpick. Not really an effective use of the Relic slot, so I’m hoping that there’s more to it.
Harston’s Paradise - Just a Shock element Hornet.
Overcompensator - Talking Butcher.
Sniper Rifle from Brick’s quest - I’ve heard rumors that it has B0re built in, but have yet to see any confirmation.
Grenade from Cassius - This one seems to be a combination Fire Burst and MIRV grenade. I actually have it, and it seems pretty straightforward, but figure I’ll double check.
Those are the ones that I have personally found. I’ve seen pictures and videos of a few others, but most of them are in Japanese or Korean, so I can’t read them.
